I am syncing to a Blackjck with WM6. I have continuing issues with activesync encountering a problem and shutting down. It seems to be with tasks and calls. When I run into this problem and look at act on the computer, all tasks are duplicated and set to one day under duration. Then I have to go in and delete the dupicates on the computer and them reload everything on the phone which entails reseting. This occurs about once a week. My default to timeless activities is 5 minute duration. Any solutions besides a new phone?
